A vulnerability was found in YunaiV/zhijiantianya ruoyi-vue-pro up to 2026.08. This affects an unknown function of the file yudao-module-infra/src/main/java/cn/iocoder/yudao/module/infra/controller/admin/file/FileController.java of the component File Upload. Performing a manipulation results in cross site scripting. It is possible to initiate the attack remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Cross-site scripting in RuoYi-Vue-Pro (all versions up to 2026.08) allows remote attackers to inject script through the File Upload component implemented in yudao-module-infra/src/main/java/cn/iocoder/yudao/module/infra/controller/admin/file/FileController.java, which is later rendered in the administrative interface without adequate output encoding. Publicly available exploit code exists and the vendor was contacted but did not respond, so no vendor patch is available at time of analysis. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires interaction with the File Upload feature implemented in yudao-module-infra FileController.java of ruoyi-vue-pro (versions up to 2026.08), where uploaded file data (such as filename or content) is later rendered in the admin/management interface without adequate output encoding, producing cross-site scripting. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely modest-severity issue that the raw CVSS 4.0 score of 5.3 already reflects. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch identified at time of analysis: the maintainers were contacted early but did not respond and no fixed version is published, so operators must rely on compensating controls. … Detailed patch versions, workarounds, and compensating controls in full report. |
